I am an ex-nikken guy, and have sold hundred of rotary tables. All you need is to make a back plate to mount your chuck, onto the table face plate/bore. As I assume the back of your chuck as a plain recess. Normally you locate backplate in the precision bore of the table, however make sure the outer backplate location diameter is about 0.015" smaller than the recess in the chuck to allow you to center the chuck on the table. Fix backplate on chuck, and nip up fastener, but don't fully tighten them, fit & check TIR, centre chuck on table, mark position table/chuck with felt tip marker, remove & tighten backplate, then refit, job done ok? |
